The tip of the iceberg was really just…the tip of the iceberg. For the second time, the R.M.S. Titanic could be seeing its last days.

A new report in the latest International Journal of Systematic and Evolutionary Microbiology says DNA research found mysterious bacteria on the hull of the sunken ship that could cause it to deteriorate to a simple rust stain in 15-20 years.

The pesky bacteria, named Halomonas titanicae, was obtained from ‘rusticles,’ the orange icicle-looking formations of rust that were collected from a previous expedition to the wreck. It does its damage by adhering to steel surfaces and spreading , and it could do so until the once glorious ocean liner is a pile of rusty dust two miles below the surface.
